Patent EP-0230752-A2 (EP)
Inventor: RICHARDS JOHN WILLIAM
IPC: H03H17/06
Filed: 1986-12-16
Abstract: A 2D-FIR filter arrangement comprises a 2D-FIR filter (26,30,32,34) operative during each of a plurality of successive clock periods equal to T (where T is the spacing of digital samples or words of an image signal) to effect filtration over a predetermined area of the image by processing n x m words of the signal, having a predetermined spatial relationship in the form of an array, to produce an intermediate word. Some of the intermediate words are stored in a partial products store (28). Control means (60) is responsive to a signal (HCF,VCF) indicating an extent to which the image is to be compressed to do two things. Firstly, it causes the FIR filter (26,30,32,34) to adopt a bandwidth which is reduced, with respect to a value for zero compression, by an extent related to the extent of compression. This reduces or prevents aliasing that otherwise would be caused by the compression operation. Secondly, it causes a plurality of the intermediate words, the size of which plurality is related to the extent of compression, to be combined (48) to produce output words (56) representation of filtration over an area of the image which is a multiple of the above-mentioned predetermined area, improving the response of the filter arrangement.

Abstract: A railway switch is mounted on y-shaped sleepers. All sleepers in the switch have a medium portion of equal slightly s-shaped configuration and length. The length of the straight and parallel ends depends on the position of the individual sleeper in the switch. The sleepers extend alternately from one outer rail in the direction to the other outer rail. The crossing piece is supported by y-shaped sleepers which underlie only the crossing piece and alternately one of the outer rails in the switch. If the switch comprises a straight and a curved line, all sleepers supporting the outer straight rail are arranged at a right angle to the straight line and protrude outwardly over the straight rail in the same length. Preferably the sleepers are composed of two s-shaped I-beam steel profiles and additional shorter I-beam steel profiles at the bifurcated straight ends, all pairs of adjacent I-beams being connected at a distance forming a slit for inserting a coach screw.

Abstract: A device for delivering therapeutic agent to a biological environment by diffusion has at least two members (10,20), one (20) of which contains the agent to be delivered, and the other (10), delay member, being substantially devoid of agent. The members are combined just prior to installation, whereupon agent diffuses from the agent containing member into the agent-free member which is in contact with the environment. The agent-free member absorbs agent, thus delaying the time at which agent enters the environment at therapeutic rates. As a result, dosage administration profiles are obtained whereby one such two-member device is installed at regular intervals, wherein dosing occurs during only a portion of the time during which the device is installed.

Abstract: An improved roadway sign (2) comprising a light retroreflective indicia region and colored retroreflective background region is provided. The retroreflective properties of the regions are selective such that the ratio of the retroreflective brightness of the indicia to that of the background is substantially larger at observation locations within the legibility zone (8) for the sign, than the ratio is at observation locations outside (12) the legibility zone. The sign is conspicuous by virtue of the bright retroreflection and distinctive color of the background outside the legibility zone, yet is legible because of the increased contrast ratio of the indicia to the background in the legibility zone.

Abstract: Acoustical coupling is proposed as a means of determining the presence and acoustical impedance if materials behind casing in cementation evaluation. Expressions for computing coupling and attenuation in multi-receiver/transmitter logging systems are analyzed in an exponential model for the spatial decay of elastic wave energy propagating axially along the casing. Amplitude change between transmitter(s) and receiver(s) is separated into a change dependent on coupling into and out of the casing wave, as well as a change related to attenuation along the casing. Coupling which is dependent on geometrical factors such as casing size and thickness, and on distribution and mechanical properties of the material outside the casing, shows principally the mechanical impedance of the material outside. Significantly, the bonding of this material to the casing is not a dominant factor for the coupling. Thus an estimation of cement strength may be made even in the presence of microannulus.

Abstract: An integral removable duplex module (B) for use in conjunction with a reproduction processor is disclosed, including two paper trays, a first (24) operable as a duplex copy buffer tray or a paper tray, and a second (22) operable as an auxiliary paper tray, each tray having a copysheet feeder associated therewith comprised of a single cam-operated mechanism having two cantilevered arms supporting constantly rotating feed rollers (422, 426) suspended above each paper tray, and associated tray elevator mechanisms, which enhances copysheet feeding when the feed rollers are pivoted toward the trays into copysheet feeding position, and maintain copysheet trays in non-feeding positions during non-feeding operation. Copysheets are received in the duplex copy buffer tray from the reproduction processor  via  a reversible exit nip (80) at the outlet of the processor, which directs sheets passed to an outlet back to a duplex module paper path, for repassing through the reproduction processor. Sheets entering the module may be directed to either the duplex copy buffer tray or a tray-less path which passes copysheets directly back to the processor. A method for operating the duplex module is described to make efficient use of the tray-less path,by directing copysheets thereto depending on the number of copies to be made. Accordingly, copysheets may be directable to the duplex tray or tray-less path at various times during any run. Further use of the tray-less path is made to improve two-up copying feature paper handling. Duplex operations are disabled on separation of the module from the reproduction processor.

Abstract: A device for adjusting the distance between a platen and a print head, with a positioning element connected kinematically to the print head and adjustable by an actuating element and with detents to lock the displacement path of the print head at a maximum clearance and at a working clearance. Adjustment in a simple manner of an optimum working clearance for the relevant kind of record carrier is achieved by connecting the actuating element (9, 29, 33) to the positioning element through a slipping clutch (12, 31) which slips in the adjustment direction when a pre-determined level of adjustment force is exceeded, setting the available displacement path of the actuating element (9, 29, 33) to a valve greater than the adjustment range of the positioning element (6, 27) in both directions in the sense that a further movement of the actuating element (9, 29, 33) relative to the positioning element (6, 27) is possible both when the print head (3) bears against the record carrier (1) inserted in front of the platen (2), when the free clearance is achieved and by achieving the locking of the working clearance by means of a retaining force acting on the actuating element (9, 29, 33). <IMAGE>

Abstract: In a cascaded system of finite-­duration impulse response filters, the transfer function of each filter relating its output data sequence to its input data sequence is selected such that elements of its output data sequence are in phase with the first element of its input data sequence. Operation of each filter other than the first cascaded filter is suppressed until it receives from the preceding filter, the first output data sequence element which is in phase with the first element of the input data sequence of the preceding stage, thereby ensuring that the first element of the output data sequence of the first filter is in phase with the first element of the input sequence to the first filter.
